Purpose

Allow for items (that have LC call numbers) to be sorted by shelving order (based upon call number and related fields)

Context

Refer to for how this field will be presented.

Scope

1. Introduce a new property for the shelving order (the definition should be read only)

2. Use the existing library to generate the shelving order (artefacts are in maven central)

3. The input to this library should be a string concatenation of the following properties: call number, volume, enumeration, chronology, copy number, suffix

4. For the call number and suffix properties, these should come from the effective call number components

5. Store the output from the library in the new property

This should be done, under the following circumstances:

• When an item is created or updated (either individually or in a batch)

• When a holdings record is updated (either individually or in a batch), all items associated with it should be updated (as this can change the derivation of the input properties)

This should be done in a similar manner to other derived properties for items

Out of Scope

• Deriving the shelving order for existing item records (this is covered by MODINVSTOR-521)

Generating the shelving order

Examples on sorted values:

h3. Complying with the library licence

Include the following in the published jar:

• a copy of the license

• a note that MARC4J is covered by it, and

• a link to the source repository on GitHub

Add https://www.mojohaus.org/license-maven-plugin/add-third-party-mojo.html to the pom.xml to automatically create a THIRD-PARTY.txt file that contains a link to https://github.com/marc4j/marc4j where the marc4j source code can be downloaded. The plugin will add THIRD-PARTY.txt to the mod-inventory-storage jar.
